Pretty nice dog having some fun.
For police work, this is a nicely trained dog - police won't bother to have that sharp, precise obedience - a lot of that is for show (as in IPO). Dog was focused on the handler, happy to perform, and under control at all times: A+
Protection - dog did what he was supposed to do: kept position while keeping an eye on the perp, reacted instantly when his handler was attacked, bit full and solid and held on even though the guy was trying to shake him off: A+
This not a dog trained to look good in competition - this dog has all the solid basics to do a job reliably. For the protection - the dog knew this was a training exercise, you can tell that he knew the person playing the bad guy, and knew there was no real threat. I think the dog did great, surrounded by little kids, working in close quarters, his focus was 100% on his task and on his handler.
When faced with a real street criminal and a real threat - you might just see a completely different dog emerge.
